Background:
Vocal cord dysfunction is an upper-airway disorder characterized by exaggerated and transient glottic constriction causing respiratory and laryngeal symptoms. Common presentation is with inspiratory stridor often in the context of emotional stress and anxiety. Other symptoms include wheezing (which may be on inspiration), frequent cough, choking sensation, or throat and chest tightness. This is seen commonly in teenagers, particularly in adolescent females. The COVID-19 pandemic has been a trigger for anxiety and stress with an increase in psychosomatic illness. Our objective was to find out if the incidence of vocal cord dysfunction increased during COVID-19 pandemic.
Methods:
We performed a retrospective chart review of all the subjects with a new diagnosis of vocal cord dysfunction who were seen at the out-patient pulmonary practice at our children's hospital between January 2019-December 2020.
Results:
The incidence of vocal cord dysfunction in 2019 was found to be 5.2%, (41/786 subjects seen) compared to 10.3% (47/457 subjects seen) in 2020, which is a nearly 100% increase in incidence (P < .001).
Conclusions:
It is important to recognize that vocal cord dysfunction has increased during the COVID-19 pandemic. In particular, physicians treating pediatric patients, as well as respiratory therapists, should be aware of this diagnosis. It is imperative to avoid unnecessary intubations and treatments with bronchodilators and corticosteroids as opposed to behavioral and speech training to learn effective voluntary control over the muscles of inspiration and the vocal cords.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
01:31Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
